Pure speculation but I believe the below teams will be in need of a head coach:
Dallas Cowboys
Chicago Bears
New Orleans Saints
New York Giants
New York Jets
Jacksonville Jaguars
Cleveland Browns
Los Angeles Rams
Out of all of those, I believe that the Rams job and the Giants job are the most attractive. Sean McVay flirted with retiring last year and may take a year off so the Rams job is 50/50. The Giants job will be filled by Bill Belichick.
So that leaves the Bears, Cowboys, Jets, Jags, Browns and Saints. And in that order is the order of attractive.
